Abstract

The invention relates to a sputtering forming technology by a rotating-drum method and a device thereof, belonging to the fast solidifying and near net-shape forming field in metallurgy of iron and steel. The invention is characterized in that the bottom of a pouring box is provided with a molten metal drainage passage; a port of the molten metal drainage passage is provided with a high temperature roller; a gap is reserved between the high temperature roller and a soleplate of the molten metal drainage passage; the front end of the soleplate of the molten metal drainage passage is provided with a baffle; the lower surface of the soleplate of the molten metal drainage passage is provided with a heater; and a sediment baseplate is arranged at the lateral side of the pouring box in front of the high temperature roller. The invention can prepare deposited blanks including plate, tube blank, composite processing piece and the like; the surface of a deposited layer is uniform; the tissue of a prepared ingot blank is more uniform; the device can prepare metal material with very thin crystal grain; and the technology has simple equipment and is convenient for continuous production.

Description

1. Technical field [0001] The invention relates to a roller sputtering forming process and device, belonging to the field of rapid solidification and near-net shape processing in iron and steel metallurgy. 2. Background technology [0002] The technology of pulverizing molten metal particles for deposition belongs to the field of rapid solidification technology, and centrifugal jet deposition is one of the technologies. The principle of centrifugal spray deposition is: after the molten steel is melted in the crucible, it is transported out through the bottom catheter, and the molten steel drops onto the centrifugal deposition plate at the bottom, and the deposition plate rotates at high speed to centrifugally atomize the metal liquid, and the metal liquid The drop cools rapidly during the flight, and the semi-solid atomized particles are finally deposited on the cold substrate. The substrate moves up and down in the furnace body, and the continuously deposited particles are ...
